Description

[0001] Remote hitting device for safety diagnosis [

The present invention relates to a remote striking device for safety diagnosis for inspecting a structure through a hitting sound generated by striking a structure with uniform and strong force without approaching a structure located in a high position and a dangerous area.

Generally, when a rigid structure is priced at a hammer or the like, a clear sound is produced. When a rigid or cracked structure is priced, a bass or a dingy sound is produced.

In order to obtain the convenience and reliability of the test at the same time in the inspection of the construction site, the equipment operation site, the concrete structure of the facility, or the specific member using the sound phenomenon, the Hammer Test, The members are regularly inspected to inspect more stable and efficient structures and specific members and to operate the facilities.

In particular, there is a phenomenon in which a specific vibration is emphasized depending on the strength and damage state of a structure or a specific member, and the shape of a check hammer.

Therefore, in order to measure the strength of a structure or a specific member, various types of check hammer suitable for each situation are formed and used so that the convenience and reliability of the test can be obtained at the same time.

In the hammer test, a hammer is used to apply a hitting force to a hitting area at a constant pressure, and a hitting sound generated at this time is heard to easily determine the strength, breakage, or cracking state of a structure or a specific member.

Therefore, the above-described hammer test is widely used because it can obtain reliable results without the need of directly visually judging by disassembling the related components in order to check the strength, breakage and cracking state of the concrete or specific member of the structure .

As described above, it is important that the hammer test is performed to hit the test target region with a certain pressure accurately.

Thus, the strength, breakage, and cracking state of the structure or the specific member can be easily judged according to the sound generated by hitting the region to be tested.

However, the hammer test has a problem that the accuracy of the judgment result becomes ambiguous because it is difficult to hear the sound of the hit sound due to the noise at the inspection site.

Further, since the conventional hammer test is configured to be suitable for a structure or a specific member having a low height such as a human key, there is a problem that separate equipment is required to test a structure or a specific member at a high place.

Korean Patent No. 10-1842017 (hereinafter referred to as Patent Document 2) has been proposed in order to solve the above problems.

The above-described Patent Document 2 discloses a rotary actuator for forming an upper fixture having a fixing spike at an end of a vertical support rod extending in a vertical direction, a hammer formed at one end of the upper fixture, and a stationary plate having a string connection hole formed at the other end thereof And the other end of the upper fixture includes a microphone for transmitting sound when hitting the hammer, and an operation strap for hitting the hammer on the structure.

Patent Document 2 discloses that a worker can test a structure at a high position by placing the hammer device for inspection in Patent Document 2 at a position where it is desired to be inspected and then pulling the operation cord and striking the hammer on the structure.
